The particles in a colloid remain dispersed throughout the mixture because they _____
are extremely small
Distillation can be used to separate solutions of miscible liquids because
different liquids usually have different boiling points
What happens when a supersaturated solution cools down
the solute will crystallize out of the solution
What happens when the pressure on a soda is decreased?
The solubility of a solute depends on
the nature of the solute and the temperature of the solvent
a dissolved solute that does no dissolve ions is
a nonelectrolyte
Gases are ___ soluble in warm water than in cold water
less (they are soluble in low temp, high pressure)
Adding sugar to water ___ the boiling point of the water.
increases
unsaturated
capable of dissolving more solute
saturated
reached its maximum capacity of solute, additional solute results in undissolved particles,
colligative properties
properties that depend on the amount of solute dissolved in the solution
What does more dissolved particles mean?
higher boiling point, lower freezing point
henry’s law
at a given temperature, the solubility of a gas is directly proportional to the pressure of the gas above the liquid
Why is boiling point elevation a colligative property?
It is directly proportional to the concentration of particles in a solution
